Moment-of-Inertia of Baseball Bats

Sep 04, 2008· The radius of gyration is the distance R from the pivot point where a point mass (small ball) with the same mass as the total mass M of the bat would be located, so that the moment-of-inertia of this point mass ball would be the same as the moment-of-inertia of the actual bat. I = M R 2: Radius of Gyration compared to the Balance Point.

What Is Moment of Inertia (MOI) in Golf?

May 24, 2019· "Moment of inertia, or MOI, is a property of physics that indicates the relative difference in how easy or difficult it will be to set any object in motion about a defined axis of rotation. The higher the MOI of an object, the more force will have to be applied to set that object in a rotational motion.
